Description
FIELD OF THE INVENTION
[0001] The present invention relates to a light-emitting device,
and particularly to an electronic light-emitting device that
replaces a conventional candle.
BACKGROUND OF THE INVENTION
[0002] Candlelight of candles had long been a main lighting tool of
the people for the night since the medieval times until gradually
being replaced by electric lights in the Second Industrial
Revolution (also known as the Age of Synergy). However, in addition
to emergency uses during blackout, candlelight is still widely used
in the daily life for purposes of decoration and pleasure. For
example, candles are traditionally used in ceremonial occasions
such as weddings, anniversaries and funerals, special holidays, and
religious occasions. Ornamental candles offering decorative
functions and scented candles offering different atmospheres are
now available on the market.
[0003] During the recent years, electronic candles are applied in
the conventional candle market in the view of eliminating
environment and safety issues including odor from burning and fire
accidents of conventional candles. In an electronic candle, an
electronic light source is combined with decorative pieces to
simulate glimmering and flickering effects of conventional
candlelight. However, comparing with conventional candlelight,
changes of an electronic light source and swings of decorative
pieces are too regular to provide realistic visual effect. A
market-available electronic candle, for example, an electronic
light-emitting device disclosed by China Publication No.
CN101865413A, includes a core, an enclosure and a chassis. A first
magnet and an induction coil are provided at a bottom of the core,
and a linkage rod is provided in the core. A second magnet
corresponding to the first magnet is provided at a lower portion of
the linkage rod. Above the core is a flame sheet, which is
penetrated through and suspended by a flame sheet pole. A third
magnet and a fourth magnet corresponding to each other are provided
above the linkage rod and below the flame sheet. A PCB motherboard
and a power supply unit are provided in the chassis.
[0004] When a control circuit on the PCB motherboard sends out a
pulse that passes the induction coil and the first magnet, the
second magnet at the linkage rod is swung due to magnetic
induction, which further drives the third magnet and the fourth
magnetic to produce magnetic induction, thereby swinging the flame
sheet. However, as a result of the PCB motherboard and the power
supply unit, the electronic device correspondingly has a greater
volume that occupies a greater space, and requires a larger load
and higher manufacturing costs. Further, as the flame sheet
produces limited swinging movements due to the flame sheet pole and
magnetic attraction and repulsion, the swinging movements of the
flame sheet may appear too artificial when one observes the
movements for a period of time. In addition, in an occasion where a
large number of electronic light-emitting devices are utilized,
wastes caused by a large number of the same functional elements
that have to match the sockets one-on-one are generated and burden
an addition load to the environment.
SUMMARY OF THE INVENTION
[0005] Therefore the primary object of the present invention is to
provide an electronic light-emitting device that replaces a
conventional candle and offers better utilization safety.
[0006] Details of the technical solution of the present invention
for achieving the above object and solving issues of the prior art
are described below. An electronic light-emitting device of the
present invention includes a housing. An upper end of the housing
is provided with an opening. A positioning rod is connected to and
provided at an inner side of the housing and close to the opening.
A holder provided with a through hole is penetrated by the
positioning rod and thus mounted on the positioning rod. An upper
end of the holder is provided with a flame decoration sheet that is
extended to expose outside the opening. A light-emitting unit is
provided at the inner side of the housing and close to the opening.
A radiating surface of the light-emitting unit is corresponding to
a side surface of the flame decoration sheet. A swinging member is
provided at the inner side of the housing and away from the
opening. Each of two sides of the swinging member is provided with
a shaft connected to the inner side of the housing. The swinging
member is connected to a magnetic element. An upper end of the
swinging member is extended to form an extension section that
correspondingly touches and pushes a lower end of the holder. The
driving member is provided at the inner side of the housing to
correspond to the magnetic element. A lower end of the housing is
connected to a seat.
[0007] The electronic light-emitting device of the present
invention achieves the following effects.
[0008] First of all, the electronic light-emitting device of the
present invention is capable of replacing conventional candle, and
thus preventing fire accidents and human body burnt hazards.
[0009] Secondly, when utilizing the electronic light-emitting
device of the present invention, as the through hole of the holder
is abutted by a pointed section of the positioning rod, and
swinging movements of the holder are produced from the swinging
member touching and pushing the holder, the flame decoration sheet
of the holder is driven to produce irregular movements that better
simulate real visual effect of a flickering and swaying flame.
[0010] Further, according to the application of the seat, the
electronic light-emitting device may be implemented in a separate
or integral form. With the swinging member, the flame decoration
sheet may have a swinging or non-swinging design. In the integral
form, a power supply unit and a control unit are provided in the
seat to control the power supply of the electronic light-emitting
device. In the separate form, the seat is applied to operate with a
socket. For example, a plurality of sockets that can be
correspondingly inserted by the pins respectively are provided at
the lamp seat. As such, the lamp seat may be inserted by a
plurality of electronic light-emitting devices. With the control
unit and the power supply unit in the lamp seat, the power supply
and the swinging changes of the electronic light-emitting devices
can be controlled at the same time, thereby reducing volume, weight
and production costs of the electronic light-emitting device of the
present invention.
[0011] The foregoing, as well as additional objects, features and
advantages of the invention will be more readily apparent from the
following detailed description, which proceeds with reference to

electronic light-emitting device 1 includes a housing 2, a
positioning rod 3, a holder 4, a light-emitting unit 5, a swinging
member 6, a driving member 7, and a seat 8.
[0024] The housing 2 includes a first cover 21 and a second cover
22 that can be correspondingly fastened to each other. An embedded
groove 23 is provided on an upper periphery of each of the first
cover 21 and the second cover 22. A fastening ring 24 is coupled on
and fastened around the embedded grooves 23 of the first cover 21
and the second cover 22. An opening 25 is provided between an upper
end of the first cover 21 and an upper end of the second cover
22.
[0025] The positioning rod 3 is disposed at an inner side of the
housing 2 and close to the opening 25. Further, the positioning rod
3 has two ends respectively connected to an inner side of the first
cover 21 and an inner side of the second cover 22, and a middle
part of an upper end provided with a protruding pointed section
31.
[0026] The holder 4 is provided with a through hole 41. A top wall
of the through hole 41 is provided with a recess 411 that
corresponds to the pointed section 31. An upper end of the holder 4
is provided with a flame decoration sheet 42. A lower end of the
holder 4 has a protrusion 43. The holder 4 is penetrated by the
positioning rod 3 via the through hole 41 to be mounted on the
positioning rod 3, and the flame decoration sheet 42 passes through
the opening 25 to be exposed outside the housing 2. The recess 411
of the through hole 41 is abutted by the pointed section 31 of the
positioning rod 3, such that the holder 4 forms irregular movements
on the positioning rod 3.
[0027] The light-emitting unit 5 is disposed at the inner side of
the housing 2 and close to the opening 25, and is clamped between
the first cover 21 and the second cover 22 to be fastened in the
housing 2. A front end of the light-emitting unit 5 is provided
with a convex lens 51 through which a radiating light area can be
enlarged. A radiating surface of the light-emitting unit 5 forms an
included angle .theta. between 25 and 30 degrees against a vertical
central axis of the housing 2. As such, the radiating surface of
the light-emitting unit 5 radiates upon a side surface of the flame
decoration sheet 42 to simulate flames of candlelight.
[0028] The swinging member 6 is a soft rubber and disposed at the
inner side of the housing 2 and away from the opening 25. Each of
two sides of a lower end of the swinging member 6 is provided with
a shaft 61. The shafts 61 are connected to the inner side of the
first cover 21 and the inner side of the second cover 22,
respectively. One end of the swinging member 6 away from the shafts
61 is provided with a magnetic element 62 being a magnet. An upper
end of the magnetic element 62 of the swinging member 6 is extended
to form an extension section 63 that corresponds to the protrusion
43. Thus, the shafts 61 and the housing 2 are connected to allow
the swinging member 6 to perform axial rotation movements. Further,
with corresponding contact between the extension section 63 and the
protrusion 43, the holder 4 is driven to swing.
[0029] The driving member 7 is a coil and disposed at the inner
side of the first cover 21 to correspond to the magnetic element
62.
[0030] The seat 8 is provided at a lower end of the housing 2, and
is coupled on and fastened around a lower periphery of the first
cover 21 and a lower periphery of the second cover 22. A bottom of
the seat 8 is provided with a pin which is electrically connected
to the driving member 7 and the light-emitting unit 5.
[0031] With the foregoing elements of the present invention, as
shown in FIG. 3B and FIG. 3C, the pin 81 receives a signal pulse,
and magnetic attraction is produced through induction between the
driving member 7 and the magnetic element 62, such that the
swinging member 6 produces axial rotation movements. Further, as
the swinging member 6 is made of soft rubber, when the swinging
member 6 swings to make the extension section 63 contact the
protrusion 43 to push the holder 4, the volume caused by touching
is effectively reduced. Further, the flame decoration sheet 42
exposed outside the opening 25 forms irregular swinging movements
at different angles as the recess 411 of the through hole 41 of the
holder 4 is abutted by the pointed section 31 of the positioning
rod 3, thereby reinforcing realistic visual effect of a swaying and
flickering candle flame. In addition, with the light from the
light-emitting unit 5 radiating upon the flame decoration sheet 42,
illumination as well as swinging visual effect of candlelight are
simulated.
[0032] In the present invention, the electronic light-emitting
device 1 is electrically connected to a socket 91. Referring to
FIG. 4, in an embodiment, a lamp seat 9 of a lamp is taken as an
example. The lamp seat 9 is provided with a plurality of sockets
91, and includes a control unit 92 and a power supply unit 93
therein. The control unit 92 is electrically connected to the power
supply unit 93 and the sockets 91 to send signal pulses. The pins
81 of the electronic light-emitting devices 1 are correspondingly
inserted and connected to the sockets 91 of the lamp seat 9. A
surface of the electronic light-emitting device 1 is further coated
by a cladding layer 20 which appears as a decoration that imitates
a candle body. The power supply and the swinging movements of the
electronic light-emitting device 1 can be at the same time
controlled by the control unit 92 and the power supply unit 93 of
the lamp seat 9. Further, with the electronic light-emitting device
1 and the lamp seat 9, the electronic light-emitting device 1 alone
may be replaced when this electronic light-emitting device 1 is
malfunctioning or damaged, so as to overcome the issue of wastes
caused by a large number of the same functional elements that have
to match the sockets one-on-one as in an occasion where a large
number of electronic light-emitting devices are utilized. In the
present invention, however, the seat 8 of the electronic
light-emitting device 1 and the lamp seat 9 are separately
disposed, the electronic light-emitting device 1 of the present
invention offers reduced volume, weight, production costs and
selling prices, and achieves effects of promoting environment
protection as well as preventing fire accidents and human body
burnt hazards.
[0033] In another embodiment, the seat 8 of the electronic
light-emitting device 1 combines functions of the lamp seat 9.
Referring to FIG. 5 and FIG. 6, a control unit 92 and a power
supply unit 93 are provided below the seat 9. The control unit 92
is electrically connected to the power supply unit 93, the driving
member 7 and the light-emitting unit 5. The power supply and
swinging movements of the electronic light-emitting device 1 are
directly driven by the control unit 92 and the power supply unit
93. As such, the electronic light-emitting device 1 of the present
invention may form an integral set that offers consumers with an
additional option to select from.
[0034] In yet another embodiment of the present invention, an upper
end of the housing 2 of the electronic light-emitting device 1 is
provided with an opening 25 and a flame decoration sheet 42 exposed
outside the opening 25. A light-emitting unit 5 is provided at an
inner side of the housing 2 and close to the opening 25. A
radiating surface of the light-emitting unit 5 is corresponding to
a side surface of the flame decoration sheet 42. A lower end of the
housing 2 is connected to and provided with a seat 8, which may be
implemented with the lamp seat 9 in a separate or integral form as
in the foregoing description, as shown in FIG. 7 and FIG. 8. Thus,
the electronic light-emitting device 1 of the present invention has
a fixed flame decoration sheet 42 that does not swing to serve as a
night lamp. The seat 8 of the electronic light-emitting device 1 of
the present invention is further electrically connected to the
light-emitting unit 5 to provide consumers with another choice to
select from.
